Products Description of Aluminum oxide CAS#98-92-0
Industrial-grade nicotinamide has a minimum purity of 99%, appearing as an odorless, flammable white crystalline powder. Its key physicochemical parameters are as follows: the melting point ranges from 129℃ to 132℃, and the boiling point is 336℃; the vapor pressure is 5.6×10⁻⁵kPa at 25℃, with a relative density of 1.40 (20℃). The compound shows high solubility in water (1200g/L at 20℃) and slight solubility in ether. It maintains stability in dry air but is incompatible with strong oxidizing agents.

Product Application of Aluminum oxide CAS#98-92-0
Citric Acid Monohydrate, a naturally occurring tricarboxylic acid derived from citrus fruits, is a widely used excipient in pharmaceutical formulations, primarily leveraging its inherent antioxidant activity. It plays three core roles in drug preparations: preserving the chemical stability of active pharmaceutical ingredients (APIs), extending shelf life as a preservative, and regulating formulation pH as a reliable acidulant. Additionally, it acts as an anticoagulant by chelating calcium ions in blood, making it suitable for certain clinical and diagnostic applications.
